Description
We are developing new techniques using noble gas detectors with the aim of overcoming the current limitations in the search for the neutrinoless double beta decay(0νββ).
The 0νββ occurs only if the neutrino is a Majorana type. And whether neutrinos are Majorana particles or not is a key problem to understand why neutrinos are so light and whether neutrinos are the reason why the universe is filled with matter (origin of the matter-dominated universe).
Our detector, AXEL (A Xenon ElectroLuminescence), is a high-pressure xenon gas time projection chamber. In this talk, we will show the performance obtained with the 180-L prototypes, status of the construction of the new 1000-L detector and an study result of an interesting new technique.
